The NX Audio AX-340 is a high-precision active crossover designed for professional audio systems requiring tight frequency control and superior clarity. With flexible configurations for stereo 2-way, 3-way, or mono 4-way setups, it employs Linkwitz-Riley filters (24 dB/octave) to ensure flat summed amplitude response and zero phase difference. Ideal for live sound and permanent installations, the AX-340 offers output limiters, delay alignment, CD horn EQ, and subwoofer summing—making it an all-in-one solution for optimized system performance.
